Timber and wood-based materials are widely used for production of building structures and, in particular, for production of window units. Window glued laminated lumber is made three-ply in thickness, provided that each ply is glued of separate plies (lamellae). The article presents the procedure of calculation of production of window glued laminated lumber for building structures. Results of timber volume losses calculation for each manufacturing operation are illustrated, the needed volume of converted timber for each manufacturing operation and organization of all production in general is calculated. Loading and required quantity of the process equipment is defined. Analysis of unification of optimal cross-sections of converted timber is performed, selection of the most applicable is reasoned. Example of the process diagram of workshop for production of window glued laminated lumber is presented. Two variants of manufacture of window glued laminated lumber of converted timber and roundwood are considered. Sequence of processing of timber from raw material up to the end product is shown. Results of the study are based on the long-term manufacturing experience obtained by one of the authors at woodworking enterprises of the Russian Federation. They can be useful for practical application in organizing and planning of production of window glued laminated lumber for building structures, and they may serve as a starting point for further research in a specified direction. It is concluded that this study presents the wood consumption calculation methodology related to performance of the processing equipment specifically for production of window glued laminated lumber for building structures. The work is based on lengthy research in real production conditions.
